EDWARDSVILLE, Ill. (AP) - An Alton woman will have to serve eight years in prison for her role in a southwestern Illinois man's heroin death last summer.

The (Alton) Telegraph reports 28-year-old Mary Ellen Johnson pleaded guilty to drug-induced homicide in Madison County. As part of a plea deal, prosecutors dropped a count of unlawful delivery of a controlled substance within 1,000 feet of an elementary school.

Authorities say Johnson supplied the heroin that was used by 34-year-old Michael Johnson, who died from an overdose last July at Mary Johnson's home.
